ABSTRACT:
An electric motor assembly includes a rotor rotatable about an axis and a stator spaced radially away from the rotor. An isolation housing, configured to permit magnetic flux to flow therethrough between the rotor and the stator, is disposed between the rotor and the stator and defines an internal rotor chamber, in which the rotor is located. The isolation housing fluidly isolates the internal rotor chamber from the stator. An encapsulating cover is provided that radially and axially surrounds the stator. The cover is formed of a resin material and bonds the stator to the isolation housing to prevent relative movement therebetween.
